如何在Yii播种? [英] how to seed in Yii?

问题描述

我想知道一旦通过迁移创建表，该如何在Yii中播种? 我已经有了一个升级的方法:

I'm wondering how one can seed in Yii a table once it is created with migration? I've got a migration with an up-method:

    public function up()
{
    $this->createTable('users',array('id'=>"pk",
        'login'=>'string NOT NULL'));
    echo "table 'users' is created.\n";
    return true;
}

我也有相应的 Users 用户模型及其 CRUD操作.当我尝试使用向上方法执行另一次迁移

I've got as well corresponding Users model and its CRUD actions. When I try to execute another migration with an up-method

public function up()
{
   $user = new Users;
   $user->login = "Bob";
   return $user->save();
}

我收到以下错误: PHP错误[2]:include(users.php):无法打开流:没有这样的文件或目录 在文件MyYiiRoot \ yii \ framework \ YiiBase.php中的第421行

I get the following error: PHP Error[2]: include(users.php): failed to open stream: No such file or directory in file MyYiiRoot\yii\framework\YiiBase.php at line 421

我已经通过使用查询生成器(通过 insert 命令)成功达到了预期的结果，但我希望有更好的解决方法.

I've managed to achieve the desired result by using query builder (by means of insert command), but I hope there is a nicer way out.

推荐答案

使用

public function safeUp()
{
   $this->insert('users',array(
      'login'=>'Bob'));
}

您还可以执行更新，删除和许多其他操作.查看 http://www.yiiframework.com/doc/api/1.1/CDbMigration有关更多信息

You can also do update, delete and a host of other actions. Look at http://www.yiiframework.com/doc/api/1.1/CDbMigration for more information
